The Nikwax Tech Wash is the ideal product for the routine washing of all non-wax waterproof garments. Nikwax Tech Wash is an easy-to-use, non-detergent cleaner for waterproof clothing and equipment such as tents and backpacks, and can be used in the washing machine or by hand with no need for tumble drying. If your technical wear has taken a battering from the elements, then use the Nikwax Tech Wash to gently lift out dirt while revitalising all water repellent finishes and maintaining the cosmetic appearance of the item.
